ChatGPT uses Bing
ChatGPT doesn't use Google. It uses Bing.
This is the cheapest gap in AI visibility to close and the one almost nobody has looked at. It is free, it takes about twenty minutes, and it does not need a developer.
The free test
See what AI actually says about your business
We ask GPT-5, Claude and Gemini the exact question your next customer is about to type, live, while you watch. Then we tell you whether they named you, named a competitor, or had never heard of you.

This is a real test, not a lead magnet with a generic PDF at the end. You see the actual answers the models gave, the businesses they named instead of you, and what on your own site is causing it.
This is the shortest, cheapest, most overlooked win in the whole of AI visibility, and it comes down to one sentence.
When ChatGPT goes looking on the live web, it searches Bing. Not Google.
If you have spent ten years and real money making Google happy, none of that effort went into the index ChatGPT actually consults when a customer asks it for a recommendation. It is not that your SEO was wasted. It is that it was filed in the wrong cabinet.
Why this hits a local business hardest
A national brand is in Bing because it is in everything. Nobody has to think about it. A local service business is in Bing only if Bing happened to find it, and Bing crawls less aggressively than Google does.
A site redesign, a domain change, a move from one platform to another: Google usually catches up within days, because it is watching. Bing can be months behind, can be holding an old version of your site, or in the case of a newer business can simply never have got round to you at all.
We have tested businesses that sit on page one of Google for their main service and, asked the equivalent question, ChatGPT cannot produce them. The site is fine. Google knows it perfectly well. Bing has a copy from two redesigns ago.
The honest caveat, because most articles on this overstate it
Bing is not the whole story. ChatGPT also draws on what the model absorbed during training, and OpenAI runs its own crawler alongside its use of Bing. Being in Bing is not a switch that puts you into every answer. It removes one specific, common and entirely fixable reason you cannot appear.
And this is only ChatGPT. Gemini is Google's and reads Google's understanding of the web. Claude runs its own search. Perplexity runs its own crawler. So the conclusion is not “move from Google to Bing”, which would just be swapping one blind spot for another. It is that you have been working one index when there are several, and the one you have never looked at sits behind the assistant with the largest share of AI referral traffic by a wide margin.
Google knows exactly where you are. Nobody asked Google.
This is the strangest part of the whole shift. A business can be thoroughly findable, well reviewed, ranking honestly, and still absent from the answer, because the question went somewhere that was never looking at the place it is listed.

Answers to: “who’s the best near me?”
What to do about it, this afternoon
All of this is free and none of it requires a developer. Budget about twenty minutes for the first pass.
1. Find out what Bing currently has
Go to bing.com and search site:yourdomain.com. That shows you every page of yours Bing knows about.
Three outcomes, and each means something different:
- Nothing at all. Bing has never indexed you. This is common for sites under about two years old, and it is the single biggest finding on this page.
- A handful of pages, and they look old. Bing has a stale copy. Check whether the titles and descriptions match your current site.
- Everything, current. Good. Move down to step four.
2. Open Bing Webmaster Tools and verify the site
It is free, at bing.com/webmasters. If you already have Google Search Console, there is an import option that carries your verification and your sitemaps across in a couple of clicks, which is by far the fastest route. Otherwise verification works the same way Google's does: a file, a meta tag, or a DNS record.
3. Submit your sitemap
Your sitemap is almost always at yourdomain.com/sitemap.xml. Paste that URL into the Sitemaps section. This is the step that turns “Bing might find me eventually” into “Bing has been handed a list of every page I have”.
4. Use URL submission on the pages that earn money
Bing lets you submit individual URLs for immediate crawling, with a generous daily quota. Google has nothing comparable at this scale. Spend it on the pages a customer would actually be sent to: your main service pages, your service-plus-city pages, your contact page. Not your blog archive.
5. Check that bingbot is not blocked
While you are in your robots.txt for the AI crawlers, confirm bingbot is not disallowed there either. It occasionally gets caught up in the same over-broad plugin rules. The crawler blocking page covers how to read that file.
What changes, and how fast
Of everything in this cluster, this is the fastest-moving item, because you are not waiting on reputation or on other people writing about you. You are telling an index that already works that you exist.
Typically Bing picks up a submitted sitemap within days. Whether that then shows up in a ChatGPT answer depends on everything else: whether the pages are readable, whether they state the service and the city, whether anyone else corroborates you. Bing indexing is the gate. Walking through it is a separate matter.
Which is the honest summary of this whole page: getting into Bing will not by itself make ChatGPT recommend you. Not being in Bing can absolutely stop it. It costs an afternoon and nothing else, which makes it the easiest decision on the list.
Common questions
Does ChatGPT use Google or Bing?
For live web browsing, ChatGPT searches Bing's index rather than Google's. It also draws on what the model absorbed in training and on OpenAI's own crawling, so Bing is not the only input, but it is the search index behind live lookups.
This is why a business optimised only for Google can be nearly invisible in ChatGPT.
How do I check if Bing has indexed my site?
Search Bing for site:yourdomain.com. That lists every page of yours it knows about.
Nothing back means Bing has never indexed you, which is common for sites under about two years old. Results that look out of date mean Bing is holding a copy from before your last redesign.
Is Bing Webmaster Tools free?
Yes, completely. If you already use Google Search Console there is an import option that carries your verification and sitemaps across in a couple of clicks.
It also offers URL submission with a generous daily quota, which has no real Google equivalent at that scale. Spend it on the pages that earn money.
If I get into Bing, will ChatGPT start recommending me?
Not on its own. Being in Bing removes a common blocker rather than creating a recommendation.
Whether a model then reaches for you depends on whether your pages are readable, whether they state plainly what you do and where you do it, and whether anyone else describes you that way. Bing indexing is the gate, not the destination.
Should I stop working on Google SEO then?
No, and that would be exactly the wrong lesson. Gemini reads Google's understanding of the web, and Google is still where most search happens.
The point is that you have been working one index while several now matter, and the one almost nobody looks at sits behind the assistant with the largest share of AI referral traffic.
Keep going
Getting into the index is the gate. What happens once you are through it is the rest of this cluster.
